To all whom it may concern I Be it known that I, 'JoHN L. KozMonsKI,

This invention relates to *a hypodermic syringe caseand has for its object to provide a compact, light, convenient and hygienic.

case for transporting and protecting" a hypo dermic syringe and which also comprises compartments suitable for containing vials for medicines and for syringe needles. 1

The invention ;-is" an improvement upon the hypodermic syringe case for which U. S.

Letters Patent No. 650,348; were issued to andto Charles Witkowski May 22, 1900, which reference maybe had.

The object of thepresent invention is to A overcome certain defects in the syringe case r the barrel ofjthe'syringefrom being rotated" of the Witkowski patent, such", for example, as providing means to'prevent the syringe from-being ejected from the tube by the spring whichimparted a longitudinal movement to said tube'containing 'the'barrelof said syringe; I

The object of theinvention isfurther to provide a stop which'will not only prevent the syringe frombeing ejected from the 'slidable tube'by the action of the spring,

but'which will also act as a stop to prevent when the same i s-be'ingengaged with or dis- 'device. v 7

'Again' the" object ofthe invention is to provide a cap Twhich is soformed' as to engage the upper end of the holder in a man- The invention consists in a hypodermic syringe case formed and constructed. as

hereinafter described and particularly in the combinationof parts setiforth in the claims.-

-Referring to the drawings:

Figure 1 is a front elevation of my improved hypodermic syringe case. 1

Fig. 2 is a sectional elevation taken'on line 2'2 of Fig. 1-.

Fig. 3 is a, plan view of the same.

Fig. 4 is a sectional plan taken on line 4-4c of Fig. 1.

"Fig. 5 is a detail sectional elevation taken on line5 5 of Fig. 1.

Like; numerals refer to like parts throughout the several views of the drawings.

In the drawings, 6 is the holder, prefer- :ablyforme'd in one piece of a compound known as bakelite, or hard rubber. v cap for said holder consisting of a top 8 having a flange 9 thereon which extends around the entire cap and closely fits the upperend 10-of the holder 6. Theflower edge of the flange 9 abuts against a fiangell on'the holder 6. A tube 12 is fastened to the top 80f thecap .7 and projects into a centrally disposed compartment 13 provided inthe holder 6.

Asyringe 14 has a barrel 15 which terminates'at'its lower end in a screw-threaded nozzle"16.. Said nozzle has screw-threaded againstthe lower end of the tube 12, where.

bysaid tubeand the cap 7 together with. the syringe contained in said 'tube, are"moved lon'giti'idinally and outwardly from the compartrnent 13 of the holder 6.

The tube- 1 21has.a screw 20 fast thereto and'projecting'into faslot which has a v'erti cal 'por'tion'21' and an inclinedportion 22, so

that when, the tube is moved upwardly or outwardly by the spring 19, said tube and cap to which it is attached, together with the syringe, will first move upwardly in] a 8O engagement with a spindle 17 which isfastened to a l n0b.18, said knob forming an externally accessible means" by which the" vided comprising two arms 24 and 25. ex-.

straight line and after the flange 9 has become disengaged from the holder 6 the screw 20 will engage the inclined portion 22 a of the slot'and cause the tube and'cap, together with the syringe, to be turned at right anglesto their formerpositions.

When the. tube and capare. thnspartlyejected from the holder 6 and arestopped by the screw 20 striking the upper end of the incline 22, the tendency is for the syringe 1 1 to flyoutofits compartment l3--and per haps fall on the floor, whichis very. undes1rable, and to prevent this a stop 23 is protending. at right angles to. the. top 8 of the cap 7. The arm 25 terminates at 1ts upper end ina lateral extension 26, there being a space 27 between thefree ends of thearms.

2l and 25.

The barrel 15 has a pain of arms 28-and 29 extending laterally thereiirom. The arm 28 projects normally between the arms 24 and 25. When the tube and cap have,been moyed outwardly, as hereinbefore described,

and come to a stop, if the syringe, due tofits momentum, continues said outward movement the, ar1n28 W1ll engage the, lateral ex;

tension 26 on the arm 25. and thus the syringe will be prevented from;being.ejected from the tube 12; When, however, it is de-. sired to remove the syringe from. the tube 12, the same is partially rotated to allow the arm 28 to pass throughthe space 27 and then the syringe can. be withdrawn from. the.

tube12.

The holder6 is provided with a plurality of compartments 30, preferably an equal;

number on each side 01": the compartment 13..

The open upper ends of these compartments are closed. by the cap 7 and said compartments are adapted to, contain vials31 containing medicine or hypodermic needles.

The general operation of the device hereinbefore specifically and to some extent in general described is as follows: Assuming theparts to be in the position illustrated in Figs. 1 and 2, the knob 18 is rotated to dis-,

screw then engages the inclined portion 22:

of the slot and rotates the tube 12, cap 7 and thesyringe carried by saidtube to a position at right angles to, that formerly, oocu;

pied by said'parts The syringe is held 99%. thi Re st arl? ma a e fir ent each, by addressing the Co m 01- Beware] scribed is performed andthe. partsloekediin;

position by means of the; spindlelT, which is rotated td engage the,screw-threaded nozzle- 16 by the knob 1'8.-

Having thus. described my invention,;

what I claim and desire by LettersjPatent tosecure is v f 1. A hypodermic syringe combination, a holder,- a cap. for. saidjholder, a tube. fast to said cap. andslidable in, ELGOIHT pertinent in said; holder, said'tube adapted;

to. receivethe barrel of a syringe, a spring in said compartment adapted-to move said tube outwardly, an externally accessiblecase having, j in;

locking device within said compartmentadapted to engageeand retain. said barrel in said compartment against theaction. of said spring, anda stop; on said' cap, adapted to; engage an arm n said barrel and retam.

said barrel in said tube. v

2. A hypodermic syringe case hav ng, in combination, a holder, a cap forsaid holder,

a tubev fast to said capgand; slidable in a. compartment in said, holder, said tube. adapted to receive the barrel of a syringe, a" spring in said compartmentadapted to move said tube outwardly, an. externally accessiblev locking device within said compartment adapted. to engage and; retain said barrel in said compartmentagainst the action of said..

spring, and a stop on said cap comprising twojarms extendingat right angles .to the top 01. said cap, and. between which; an arln;

on saidbarrel is adapted .to project one. of; saidarms on said capterminating ina lateral; extens on pro ecting toward the other of said arms, there being a space between e the freeends of said arms throughwhich the army on saidgbarrel maypassto disenegage the same fromsaid stop.

In testimonywhereof I have hereunto-set.

my hand in presence of two subscribingwitnesses. V
